Orok (also Ulta ульта, or Uilta, Ujlta уйльта) is a language of the Manchu-Tungus family spoken in the Poronaysky and Nogliksky Administrative Divisions of Sakhalin Oblast, in the Russian Federation, by the small nomadic group known as the Orok or Ulta.
Orok is closely related to Nanai, and is classified within the southern branch of the Manchu-Tungus languages. Classifications which recognize an intermediate group between the northern and southern branch of Manchu-Tungus classify Orok (and Nanai) as Central Tungusic. Within Central Tungusic, Glottolog groups Orok with Ulch as "Ulchaic", and Ulchaic with Nanai as "Central-Western Tungusic" (also known[by whom?] as the "Nanai group"), while Oroch, Kilen and Udihe are grouped as "Central-Eastern Tungusic".
The language is critically endangered or moribund. According to the 2002 Russian census there were 346 Oroks living in the north-eastern part of Sakhalin, of whom 64 were competent in Orok. By the 2010 census, that number had dropped to 47. Oroks also live on the island of Hokkaido in Japan, but the number of speakers is uncertain, and certainly small. Yamada (2010) reports 10 active speakers, 16 conditionally bilingual speakers, and 24 passive speakers who can understand with the help of Russian. The article states that "It is highly probable that the number has since decreased further."
Orok is divided into two dialects, listed as Poronaisk (southern) and Val-Nogliki (northern). The few Orok speakers in Hokkaido speak the southern dialect. "The distribution of Uilta is closely connected with their half-nomadic lifestyle, which involves reindeer herding as a subsistence economy." The Southern Orok people stay in the coastal Okhotsk area in the Spring and Summer, and move to the North Sakhalin plains and East Sakhalin mountains during the Fall and Winter. The Northern Orok people live near the Terpenija Bay and the Poronai River during spring and summer, and migrate to the East Sakhalin mountains for autumn and winter.
The letter "en with left hook" is contained in Unicode since version 7.0.
In 2008, the first Uilta primer was published to set a writing system and to educated local speakers of Uilta.
